Reissue
9-610 VPatch Out Of Range RAP
The measured toned ADC patch was to light.
Initial Actions
• Refer to BSD 9.8 and BSD 9.15 for the following procedure.
• Clean the ADC Sensor.
• Clean the IBT Belt.
• Check that P/J13
9 on the ADC Sensor PWB, IBT connector J702A, J702B and P/
J416A on the IOT Drive PWB are firmly connected.
Procedure
Perform the following in the order listed.
• Go to the IQ 38 Charge Corotron HVP
S RAP and check the Charge Corotron HVPS for
proper operation.
• Ensure that the Charge Corotron Wire and Grid are in good condition.
• Go to the IQ 37
Developer Bias HVPS RAP and check the Developer Power Supply for
proper operation.
•Go to Flag
7 and Flag 8 on BSD 9.8. Check the wires for an open circuit or a short circuit.
If the wires are good, replace the ADC Sensor (PL 7.5). If the problem continues, replace
the IOT Drive PWB (PL 9.2).
• Replace the Xerographic CRU (Drum) (Section 6, M
achine Consumables).
9-612 TRC RADC Out Of Range RAP
